Description

Technical Field

[0001] This utility model relates to the field of railway sleeper stop technology, specifically a telescopic railway sleeper stop device. Background Technology

[0002] Telescopic sleeper stop devices are functional devices used in railway track systems to limit the longitudinal or lateral displacement of sleepers, while allowing them to undergo reasonable expansion and contraction within a certain range due to factors such as temperature changes and train loads. Their core function is to release or absorb the deformation stress of the track system through an adjustable expansion and contraction mechanism, while ensuring the stability of the track structure, thus preventing structural damage caused by rigid constraints. They are suitable for seamless tracks, ballastless tracks, and other scenarios where high track displacement control is required.

[0003] The working principle of the telescopic sleeper stop device is based on a "finite constraint + elastic buffer" mechanism. When the sleeper experiences longitudinal or lateral displacement due to temperature changes or train loads, the telescopic components of the device allow the sleeper to move freely within its design range, avoiding stress concentration caused by rigid obstruction. When the sleeper displacement exceeds a safety threshold, the stop components of the device restrict further sleeper movement through contact or mechanical locking, preventing track structure instability. Some devices integrate elastic elements to absorb vibration energy and buffer impact forces during displacement, reducing damage to the sleeper and foundation from high-frequency loads, while also reducing noise.

[0004] Currently, during the transportation of railway sleepers, wooden strips are typically inserted through the holes between the fasteners on the sleeper's surface as a stopping device. This device is effective in securing the sleepers laterally. However, in actual transportation, the inertia from braking and the friction and impact between adjacent sleepers can damage them, affecting the safety of the project. Existing sleeper stopping devices do not offer an effective solution to address these impacts between adjacent sleepers. Therefore, this invention provides a telescopic sleeper stopping device that provides collision protection for adjacent sleepers during transportation and is easy to store, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A telescopic sleeper stop device includes a base plate, a mounting frame mounted on the surface of the base plate, a bearing and a drive motor installed inside the mounting frame, a lead screw installed at the output end of the drive motor, a nut sleeved on the outside of the lead screw, an electric telescopic rod installed on the surface of the nut, an electric rotating shaft installed at one end of the electric telescopic rod, and a hook installed on the surface of the electric rotating shaft.

[0009] Furthermore, a groove B is formed on the surface of one end of the base plate, and a protrusion is installed on the surface of the other end of the base plate. The protrusion and the groove B have the same shape and size.

[0010] Furthermore, the surface of the mounting bracket is provided with a guide groove, and the surface of the nut is equipped with a guide slider.

After each layer of sleepers is laid, the drive motor, lead screw, and electric telescopic rod cause the hook to descend to the surface height of stop bar A.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figures 1-2 As shown in the figure, the telescopic sleeper stop device provided in this embodiment of the utility model includes a base plate 1. The material of the base plate 1 needs to have characteristics such as high strength, high toughness, and reliable weldability, for example, high-strength alloy steel, alloy structural steel, etc. The above-mentioned technical features are all mature existing technologies, which are technical solutions that are not difficult for those skilled in the art to obtain or conceive of. Those skilled in the art can make corresponding adjustments and selections based on the above-mentioned technical solutions.

[0023] like Figures 1-3 As shown, in one embodiment of this utility model, a mounting bracket 2 is mounted on the surface of the base plate 1, and a bearing 3 and a drive motor 4 are installed inside the mounting bracket 2. A lead screw 5 is installed at the output end of the drive motor 4, and one end of the lead screw 5 is connected to the bearing 3. A nut 6 is sleeved on the outside of the lead screw 5, and an electric telescopic rod 7 is installed on the surface of the nut 6. An electric rotating shaft 8 is installed at one end of the electric telescopic rod 7, and a hook 9 is installed on the surface of the electric rotating shaft 8. A plurality of stop rods C12 are installed on the surface of the base plate 1, and a stop rod B11 is installed inside the stop rod C12. A stop rod A10 is installed inside the stop rod B11, and a tension hook hole 13 is opened on the surface of the stop rod A10.

[0024] In this embodiment, the surface of the mounting bracket 2 is provided with a guide groove, and the surface of the nut 6 is equipped with a guide slider. This design is intended to enable the nut 6 to move back and forth in a single linear direction on the surface of the mounting bracket 2.

[0025] In this embodiment, the end of the hook 9 away from the electric rotating shaft 8 has the same shape and size as the stretch hook hole 13. This design is so that the hook 9 can hook onto the stretch hook hole 13, thereby allowing the stop rod A10 and stop rod B11 to be stretched out from inside the stop rod C12 by the action of the electric telescopic rod 7.

[0026] In this embodiment, threaded grooves are provided on the inner and outer surfaces of stop rods A10, B11, and C12. This design takes into account that stop rods A10 and B11 can remain upright after being stretched out from the inside of stop rod C12. In order to form a fixed connection between the three structures, threads are provided on the inner and outer walls of the three structures, and the three are threaded together by the action of the electric rotating shaft 8.

[0027] In this embodiment, the surface of the base plate 1 is provided with several grooves A14, and the shape, size, and number of grooves A14 are consistent with those of the stop rod C12. This design means that the stop rod C12 is fixed to the base plate 1 by embedding it into the grooves A14. This design takes into account that the stop device may be damaged by impact during transportation, and this embedded and detachable fixing method can improve work efficiency for easy replacement.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment of this utility model, a groove B15 is formed on the surface of one end of the base plate 1, and a protrusion 16 is installed on the surface of the other end of the base plate 1. The protrusion 16 and the groove B15 have the same shape and size. This design is to enable several base plates 1 to be spliced ​​together by the protrusion 16 and the groove B15 at their two ends, thereby extending the area covered by the base plate 1.

[0029] The working method of this utility model is as follows: During the transportation of railway sleepers, the base plate 1 is placed on the surface of the transport vehicle, and the operator places the sleepers between several stop bars C12. After each layer of sleepers is laid, the pull hook 9 is lowered to the surface height of the stop bar A10 by the combined action of the drive motor 4, the lead screw 5, and the electric telescopic rod 7. Then, by hooking the pull hook 9 into the extension hook hole 13, the stop bars A10 and B11 are pulled out from the inside of the stop bars C12. At the same time, the rotation of the electric rotating shaft 8 stabilizes the stop bars A10, B11, and C12 by the threads and grooves on their surfaces and inner walls. This forms vertical stops between adjacent sleepers. The main function of these vertical stops is to prevent adjacent sleepers from colliding during transportation and causing damage. At the same time, the protrusions 16 and grooves B15 at both ends of the base plate 1 allow several base plates 1 to be spliced ​​together, thus reducing the size of the base plate 1 and making it easier to handle and store. Therefore, the telescopic sleeper stop device provided by this utility model achieves the effect of protecting adjacent sleepers from collision during transportation and is easy to store.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
